为了对汞进行适当管理，必须澄清排放和释放的来源以及释放的数量。我们通过测量两个固体废物焚烧设施（swift -a和swift -b）和一个燃煤发电站的实际排放水平，以及燃烧残留物和原料中的汞浓度，为马来西亚制定了汞排放清单。swift -a排放的汞浓度在1.1 ~ 27.6 μg/Nm3之间，swift -b排放的汞浓度平均为35.1 μg/Nm3。燃煤电厂排放的汞浓度估计在5.2至39.5 μg/Nm3之间。我们估计了汞在各种介质中的排放和释放，并应用物质流分析将流量和存量联系起来。2012年马来西亚的潜在总排放量估计为7.60-59.09毫克（7.60-38.09毫克，不包括手工和小规模金矿[ASGM]）。SWIFs和燃煤发电站的测量数据被用来完善马来西亚的排放清单。今后，有必要通过收集更可靠的测量数据，为马来西亚的大气排放和向其他媒介的释放建立可靠的清单。
For the appropriate management of mercury, sources of emissions and release, as well as the amounts released, need to be clarified. We developed a mercury emissions inventory for Malaysia by measuring the actual emissions levels in two solid waste incineration facilities (SWIF-a and SWIF-b) and a coal-fired power station, as well as the mercury concentrations in the combustion residues and feedstock. The mercury concentration in the emissions from SWIF-a ranged from 1.1 to 27.6 μg/Nm3, while that from SWIF-b averaged 35.1 μg/Nm3. The estimated mercury concentration in emissions from the coal-fired power station ranged from 5.2 to 39.5 μg/Nm3. We estimated the emissions and release of mercury into various media, and applied a substance flow analysis to link the flows and stocks. The total potential emissions in Malaysia in 2012 were an estimated 7.60–59.09 Mg (7.60–38.09 Mg excluding artisanal and small-scale gold mining [ASGM]). The measurements for the SWIFs and the coal-fired power station were used to refine the emissions inventory for Malaysia. In the future, it will be necessary to create reliable inventories for both atmospheric emissions and release into other media in Malaysia by collecting more reliable measurement data.
